The mayor declared that the city will not allow future Mardi Gras parties in the aftermath of violent celebrations that claimed one life and injured dozens of others. "There will be no more Fat Tuesday," Seattle Mayor Paul Schell said Wednesday. "This event as it's now set up has to end."

An estimated 4,000 people jammed the streets of the city's historic Pioneer Square neighborhood late Tuesday and early Wednesday. The celebration soon disintegrated into fistfighting, bottle-throwing and window-smashing by revelers and the firing of tear gas and rubber projectiles by police. Roving groups attacked people at random.

A 20-year-old man died Wednesday night of assault-related head injuries at Seattle's Harborview Medical Center, and a 24-year-old man who fell 30 feet off an overpass remained in critical condition with severe head injuries, officials said.

No Powerball jackpot winner

None of the tickets sold for the Powerball game Wednesday night matched all six numbers drawn in Des Moines.

Players matching all five numbers and the Powerball would have won or shared the $12 million jackpot. The prize goes to an estimated $14 million for Saturday. Tickets that match the first five numbers, but miss the Powerball, win $100,000 each, and there were four of those. They were sold in: Indiana, Kentucky, New Mexico and Rhode Island.
